New:

• Add setContentAndSnapshot to 'mosaic-testing' which returns the initial composition snapshot. This avoids a potential problem with calling setContent and then awaitSnapshot since the latter will trigger a subsequent recomposition (if needed), preventing observation of the initial state.

Changed:

• Static composable no longer takes a list. Instead, it behaves like a normal composable which only renders its function once.
• Drop use of Jansi library for supporting ANSI color output on Windows.
